IMPROVEMENT IN WHEELS FOR VEHICLES.

Specification forming part of Letters Patent No. 157,039, dated November17, 1874; application filed October 16, 1874.

CASE A.

To all whom it may concern:

Be it known that I, HENRY O. TERRELL, of Wallingford, in the county ofNew Haven and State of Connecticut, have invented certain Improvementsin OarriageWheels, of which the following is a specification:

My invention consists in the peculiar combination and arrangement of thesectional metal body, the wooden filling, and the wooden spokes, ashereinafter fully explained.

Figure 1 represents a central section of my wheel, taken longitudinallythrough the hub; Fig. 2, a section of the wheel, taken transverselythrough the hub; Fig. 3, a side view of the disconnected sections of themetal body; Fig. 4, a perspective view of one end of the body and itswooden filling.

A represents a metal ring or annulus to encircle the hub, provided withstraight mortises a to receive the spokes, the mortises being arrangedso closely together that the partitions between them taper down to athin inner edge, and allow the spokes to come in contact with each otherfrom that point inward, as shown in Fig. 2. B B represent two metalrings or shells, provided around their inner ends with screwthreads, andscrewed into opposite ends of the ring or annulus A, as shown. Theshells B are each made of decreasing diameter toward the outer end, andare each filled with a wooden block, B, which is inserted from the innerend of the shell and forced tightly home before the shell is screwed tothe annulus A. The inner ends of the wooden blocks are made slightlyconvex or crowning, and are made to protrude inward slightly beyond theshells and the sides of the mortises, an open central space being leftbetween the inner ends of the wooden pieces to receive the spokes. Afterthe shells, with their wooden filling, are in place, the spokes, havingtheir sides properly tapered, are driven through the mortises a in theannulus into the space between the wooden blocks, so that theybear-against each other from the annulus inward, and form a solid massaround the pipe-box, as shown. By constructing the sectional body withits tapering ends screwed to the mortised annulus, the wooden fillinginserted from the inside, and the spokes driven through the annulus andwedged tightlyagainst each other, andbetween the two parts of thefilling, a wheel is produced which is cheap, strong, light, and neat inits appearance. It is obvious that, instead of screwing the two shellsto the annulus A, one of them may be formed solidly thereon and in onepiece therewith.

1 am aware that a mortised annulus is old; that a shell containing awooden filling is also old, and that it is old to have the inner ends ofthe spokes wedged together; and I lay no claim to these features, exceptwhen combined and arranged as shown.

Having described my invention, what I do claim is The combination of themortised annulus A, the tapering shells B, one or both screwed thereto,the wood filling (J, and the spokes D, driven through the annulusbetween the two parts 0, and forming a solid body around the axle-box.
